Study on the Performance of HDP Asphalt Rubber Mixture

HDP rubber asphalt mixture is made of rubber asphalt with a certain amount of HDP additive. The HDP rubber asphalt by Marshall design method with ratio design, of Marshall specimens tested the related technical indicators, to determine the optimum mix amount of HDP, aggregate synthesis of gradation and mixture of optimal asphalt aggregate ratio. Through the indoor experiment, the HDP rubber asphalt mixture material of rutting test, bending test at low temperature and freeze thaw split test, evaluate the mixture road performance and verify the HDP asphalt rubber mixture material with good temperature stability and anti water damage ability.
